A man is negotiating with an auto driver for a trip. The driver starts with a quotation of Rs. 200 for the destination. The buyer responds by saying the driver was over quoting and offered to pay Rs. 140 . As they negotiated, the driver made up his mind that he would not offer the trip below Rs. 150. The passenger also was also thought to himself that he would not pay a penny more than Rs. 180 and look for another conveyance if the deal did not work. Of course the two kept these thoughts to themselves and did not share them with the other person. a) Graphically represent the above situation identifying the reservation prices of the buyer and the seller as well as the zone of agreement. (You don't need a graph paper Draw it on the answer sheet itself) [3] b) If the deal was finally stuck at Rs. 170 what are the buyer and seller surpluses? [2]
